The San Diego regional planning agency, SANDAG, has been quietly rolling out a new mobile face recognition system that will sharply change how police conduct simple stops on Americans. The system, which allows officers to use mobile devices to collect face images out in the field, already has a database of 1.4 million images and serves nearly 25 federal, state and local law enforcement agencies in the region.

Over the summer, EFF sent a California Public Records Act request to SANDAG for more information on the program. From the records we received, we’ve learned that the program, called “TACIDS” (Tactical Identification System), serves law enforcement agencies as diverse as the San Diego Sheriff’s Department, the DEA, ICE, the California Highway Patrol and even the San Diego Unified School District.
